Liquid Flow Rate Information for Couplings
Q = Flow rate in gallons per minute
The chart below shows the flow rate for CPC couplings. Each coupling was tested with water at 70°F Cv = Average coefficient across various
(21°C). To determine flow rates for specific coupling configurations use the formula at the right. flow rates (see chart)
P = Pressure drop across coupling (psi)
C V VALUES FOR 1/4" FLOW PLC COUPLINGS S = Specific gravity of liquid
